Novel Variation in the N Protein of Avian Infectious Bronchitis Virus	1996-12-15		.txt	text/plain	2317	141	66	Despite the considerable variation observed between the two virus groups, all N proteins contained a high proportion of basic residues, 80% of which were conserved in position. The N protein of all coronaviruses virus lacks a sequence of 184-196 nucleotides that has is overall very basic and in IBV contains 409 amino acids been detected in five other IBV strains. located downstream of the HVR (315 nucleotides ending The N protein of 27 strains of IBV isolated over a period at the poly(A) tail) is highly conserved in strains of IBV, of 60 years from diverse locations such as the U.S.A., the probably indicative of its role in the synthesis of negative-UK, Holland, Saudi Arabia, and Japan has been shown to strand RNA. For each virus two or more for the N proteins of IBV also contain a region of complete independent cDNA clones were sequenced using the conservation between positions 242 and 296 (4).	./cache/cord-271359-dpa8zzc3.txt	./txt/cord-271359-dpa8zzc3.txt
